The invention relates to a burner such as used for heating glass tubesfor neon signs and for other purposes when the use of the burner isintermittent.

The object of the invention is to provide a fixture or attachment thatcan be interposed between the air and gas tubes that supply the burnerand the burner itself and carries a pilot light. The device is operatedby a handle or a treadle and alternately lights the main burner or thepilot light according to the direction in which the valve is turned.

The Valve is of simple construction and is readily attached and detachedto and from the burner structure.

The invention is illustrated in the accompanying drawings in whichFigure l is a front view of a burner and showing the im proved regulatoror valve for use therewith. Figure 2 is an end View of the upper part ofFigure 1.

The main burner of my desired construction and the one illustrated issupported on a base with the supporting pipe 11 which acts as a mixingchamber for the burner 12. The gas is supplied through the pipe 13usually provided with a valve 14 and the air is supplied through pipe 15provided with a valve 16. In ordinary burners the flexible hose 17 forthe gas and the flexible hose 18 for the air are attached directly tothe burner pipes 13 and 15.

I interpose between the hose and the valves, a regulator which has twooutlets, one, 19, connected to the gas pipe 13 by the union 20 and theother, at 21, connected by the union 22 to the air pipe15. The outletsare arranged in the member 23 which with the other member 24 constitutesthe main body of the regulator. The two members are fiat and have groundfaces which abut to form a tight joint. The member 24 has two inlets oneof which is supplied with a pipe 25 to receive the hose 17 and the otherhas a pipe 26 which receives the hose 18.

The inlets and outlets in the valve members extend through theirrespective mem bers and when in line supply fuel and air to the pipes 13and 15 and thus to the main burner. When placed out of register they.one mounted so as 1930. Serial No. 461,673.

out off the supply to the main burner.' two members are rotatable onerelative to the other. They are mounted on a shaft 27 which is providedwitha spring 28 which bears on the shoulder 29 on the shaft 27 and asthe cotter pin 30 or its equivalent rests on the member 24. The member24 is kept constantly pressed against the member 23. The two members arearranged normally out of register as to the inlet and outlet openings.The spring 31 is connected to an arm 32 on the rotatable member 24 andto an arm 33 on the fixed member 23. The stud 34 on the arm 33 isengagedby a pin 35 on the member 24 to limit the rotative movement of themember 24 in one direction and by a jam 36 on the same member to limitthe movement in the other direction.

The rotatable member any suitable mechanism 37 which can be secured to afoot treadle for turning the burner on and when released allowing thespring 31 to the main burner off.

This groove connects with a small pipe39 which leads to the top of the main burner and has its end directed tothe burner surface and furnishes a pilot light at the end 40. The pipe39 may have a cock41 for controlling the amountof flame at the pilotlight.

The operation is evident and when the main burner is shut ofl' byreleasing the treadle and the spring 31 holds the inlet and outletportsof the valve out of register, the
